the ordinary snbreciimbent pubescence. In the form of the genital 

 armature this genus differs greatly from any of those allied to 

 Cistela, for in the male this part is not at all bilobed, and, what is 

 still more exceptional in the family, it is more strongh^ sinuate at 

 apex in the female than in the male; it is almost equall}" exposed 

 and prominent in both sexes. 



This genus differs from the European Cteniopus in having the 

 anterior coxae more widely separated, in the short third antennal 

 joint, in its unextended front, and in the longer l)asal joint of the 

 hind tarsi. 



Andrimus will probably prove to be a moderate!}' large genus in 

 our Gulf States, but the species are rather closely allied among 

 themselves, and may be difficult to discriminate from description, 

 especially as there is nearly always more plasticity and specific 

 variability in the genera with non-lobed tarsi, than in the others. 

 The material which I have examined indicates five species, appa- 

 rently without much doubt; these may be distinguished b\' the 

 following characters : — 



Basal angles of the protliorax prominent laterally Iliurrayi 



Basal angles not prominent. 



Humeri very narroAvly exposed at base .'bruniieilS 



Humeri widely exposed at base. 



Basal pronotal fovea; almost obsolete concolor 



Basal fovefe small but deep and distinct. 



Eyes in the male separated by their own width liigresceilS 



Eyes in the male separated by distinctly less than their own width.

 A. limrrayi Lee. — New Spec. Col., 1866, p. 141 (Cteniopus). — Oblong- 

 oval, bhiniui; and rather pale piceous-browu throughout ; pubescence rather 

 long, semi-erect and sparse on the elytra. Head nearly flat above, with a 

 transversely oval, deep impression involving the base of the epistouia and 

 margin of the front ; surface rather finely but deeply, somewhat densely punc- 

 tate, the punctures all distinct ; eyes separated by their own width, bordered 

 internally by a fine groove ; antenme scarcely one-half as long as the body, 

 slender, filiform, the third joint much more than twice as long as the second 

 and fully three-fourths as long r.s the fourth. Protliorax three-fifths wider 

 than long, rather campanulate in form, the basal angles right but distinctly 

 prominent laterally, the sides before them at first feebly sinuate then nearly 

 straight and parallel to anterior two-fifths, then strongly rounded to the apex 

 which is truncate and two-thirds as wide as the base, the latter transverse, 

 the siuuations rather narrow and feeble ; disk almost evenly convex, finely, 

 sparsely punctate, with a narrow impunctate median line ; basal fovea^^ small
